O.S. Speed B2101 buggy nitro engine

O.S. Speed B2101 buggy nitro engine

Japanese company O.S. introduce their latest competition buggy engine in the form of the B2101. Based on the experience gained with the 21XZ series the square bore/stroke engine is of a new design that allows for a more controllable bottom to mid range power, resulting in improved vehicle control. The B2101 makes use of a new crankshaft that comes with a special coating and it is tungsten balanced while a redesigned cooling head lowers the centre of gravity. The motor will not replace O.S.’s Speed 21XZ-B Spec.II as this will still be available for all drivers who seek the ultimate in bottom end power. The B2101 is set for an October release following the World Championships in Sicily.
